AI Technical Summary
Technical Problem
Existing humanoid robot arms have few degrees of freedom and low motion precision, making it difficult to achieve high-precision and complex movements. Furthermore, their leg structures are complex or have insufficient load-bearing capacity.
Method used
Design an arm with 7 rotational degrees of freedom and a compact leg structure. The arm is connected to the servo motors via 7 joints, with the centers of the servo motors approximately on the same straight line. The legs utilize three servo motors close to the torso to improve flexibility and ensure load capacity.
Benefits of technology
It achieves high flexibility and precision in the arms, and a compact structure and load-bearing capacity in the legs, meeting the requirements for the use of humanoid robots.

Abstract
According to the humanoid robot with the seven-degree-of-freedom arm, the arm has seven rotational degrees of freedom, it can be guaranteed that the centers of all steering engines are approximately located on the same straight line through the structural design of all joint bases, then the arms similar to human beings are naturally formed, and the use requirements of the humanoid robot can be met; three leg steering engines at the upper ends of the legs are used for improving the action flexibility of the legs, and a connecting structure of a first leg joint seat and a second leg joint seat at the upper ends of the legs can ensure that the structures of the three steering engines are compact and closer to the body position, so that the force generation of the legs is not influenced; and meanwhile, the force exerting walking of the legs is mainly realized through stretching and retracting of the first driving devices on the rear sides of the thighs and the second driving devices and the third driving devices on the rear sides of the shanks, so that the loading capacity of the legs can still be ensured.
